Best Plumbing System Inspection in Philadelphia PA

I do not recommend Zoom Drain.
Last week, I hired Zoom Drain to complete a sewer scope. After comparing a few companies on Google, Yelp, NextDoor, and local Facebook groups (most reviews were, frankly, pretty similar - a mix of positive and negative); and asking for recommendations from our agent and friends - we decided to go with Zoom because some friends had used them recently with no issues, specifically for a sewer scope (also for an older home).
I'll start with the positives: scheduling was very easy. Zoom front office staff responded quickly to my calls and were very flexible when I had to change my appointment to another day. Staff was friendly and answered my many questions (and did not seem annoyed when I called on Monday and Tuesday to confirm my Wednesday afternoon appointment).
Here come the negatives. First, Zoom's sewer scope service is more costly than the other businesses I looked into ($429, about $70-80 more). Second, Zoom could only provide 4-hour time windows (with the technician calling you when they are 30 minutes away). My agent said this is a long window for a sewer scope. (On the other hand, is it really that far off from, say, Comcast?) Third, they don't even make those time windows! As you will read below, the office staff is very limited in terms of what they can do for you when it's the day of and you want an ETA.
My experience was not great. This past Wednesday, I waited for the sewer scope technician from 2-6pm, and they never showed up. I called at 3:30pm for an update, and they said the technician was at another job but that I was the next one on his list. I called again at 5pm and received the same response. By 5:45pm, I still hadn't received my 30-minute-away call and no one at Zoom could provide me with an update. Zoom basically said the technician wouldn't be there by 6pm (the end of our 4-hour window).
While somewhat apologetic, Zoom did not offer any solutions. By this point, I had spoken with about 4-5 different people. One man was fairly curt and didn't seem to care, but all the women I spoke with (shout out to Janae (sp?) and Shannon, who were very kind!) After the current homeowners graciously allowed us to reschedule for the next day, Zoom agreed to cancel the technician for that night and send someone the next day (Thursday) between 10am-2pm. I asked (in vain) if I could get a time-certain or see if we could be first on the technician's list, but they said no.
On Thursday morning, I confirmed the 10am-2pm time frame. I called for updates at 10:30am and 1:15pm because I had not heard from the technician. Unfortunately, I got the same response - the technician was on another job and would call me when he was 30 minutes out. I was pretty anxious at this point given that the current homeowners had already made their home available in the middle of a pandemic for nearly 8 hours. Zoom front office staff transferred me directly to their dispatch so I could get a better ETA, but dispatch hung up on me twice.
I finally got a call (and text) at 1:50pm telling me that the technician was on his way to the home in No Libs --- from Bala Cynwyd. Zoom acknowledged that the technician would be there after 2pm (again, after the 4-hour window). He ultimately arrived around 2:30pm. To Zoom's credit, I was able to get a 10% discount, but only after I asked for it. They did not offer this on their own.
The technician conducted the sewer scope pretty quickly and called me (because I could not be present that day - I took the day off of work on Wednesday to meet with them) with an update to explain what the pipes were made out of. Unfortunately, he was unable to get the camera past a trap between the home and the street, so I have no idea what those pipes look like. Zoom later sent me a report (which had nothing helpful in it); an invoice (which included the information the technician explained on the phone, so this was more of a report than the actual report); and a 30-second and 90-second video of the actual sewer scope.
Overall, my experience was very stressful, and I wish I had gone with another company.
I'm sure most people who have used Zoom (including my friends) did not have an experience like mine, but I was very disappointed. My agent (as well as the seller's agent) also seemed annoyed and are not likely to recommend them either.

Terrible.  They insisted they had to come out to see the issue when I asked for pricing.  We can't give pricing over the phone because each job is unique.  When they come out the technician pulls up a menu with fixed services and fixed prices.  He gives me the price on the exact services I had asked to be quoted out earlier.  I wouldn't have taken the day off or wasted my morning if they would have just given me the prices over the phone.  They are the ones with fixed pricing and fixed services.  Be transparent!!! Feels like a scam to me.

I have three drains.  Most likely all tie together to one exit.  I informed him I already cleared each line about 50-75 feet.  It's just the exit I can't find.  Tech wants to charge me to clean 3-5 lines for $1000.  In all reality I only need one line cleaned to open the exist.  Then I ask to how much it costs to scope it.  That's $349.

Bye-bye

Great experience. Fast to respond to phone and text, thoroughly informative and did his research before coming.

We called these guys to winterize my outdoor bathroom and the plumber who came out was excellent. They scheduled him to the day after we called and was done in an hour. Now they're our go-to plumber.

Sheridan provided us with great service from start to finish.  They originally came to reseal a toilet but diligently checked out the crawl space where the pipes were and realized there was a leak that we never would have seen.  They quickly realized that the toilet was cracked underneath and were able to install a new toilet and prevent any further damage.
